of increafed irritability tending to difeafe, becaufe an increafed 

 quanity of irritative motions generally induces an increafe of 

 pleasure or pain, as in intoxication, or inflammation -, and then 

 thv. new motions are the immediate confequences of increafc-i 

 fenfation, not of increafed irritation ; which have hence been fa 

 perpetually confounded with each other. 



II. Temperament of Senfibiliiy* 



There is not properly a temperament, or a predifpofition to 

 difeafe, from decreafed fenfibility, iince irritability and not fenfi- 

 bility is immediately neceflary to bodily health. Hence it is the 

 cxeefs of fenfation alone, as it is the defedt of irritation, that moil 

 frequently produces difeafe. This temperament of increafed fen- 

 fibility is known from the increafed activity of all thofe motions 

 of the organs of fenfe and mufcles, which are exerted in confe- 

 quence of pleafure or pain, as in the beginning of drunkennefs* 

 and in inflammatory fever. Hence thofe of this conftitution 

 are liable to inflammatory difeafes, as hepatitis •, and to that 

 kind of confumption which is hereditary, and commences with 

 flight repeated hxmoptoe. They have high-coloured lips, fre- 

 quently dark hair and dark eyes with large pupils, and are in 

 that cafe fubjecr. to gutta ferena. They are liable to enthufiafm, 

 delirium, and reverie. In this laft circumlrance they are liable 

 to ftart at the clapping of a door ; becaufe the more intent any 

 one is on the pafnng current of his ideas, the greater furprife he 

 experiences on their being diffevered by fome external violence* 

 as explained in Sedt. XIX. on reverie. 



As in thefe conftitutions more than the natural quantities of 

 fenfitive motions are produced by the increafed quantity of fen- 

 fation exiiling in the habit, it follows, that the irritative motions 

 will be performed in fome degree with lefs energy, owing to the 

 great expenditure of fenforial power on _the fenfitive ones. 

 Hence thofe of this temperament do not attend to flight ftimu- 

 lations, as explained in Sect. XIX. But when a ftimulus is fo 

 great as to excite fenfation, it produces greater fenfitive actions 

 of the fyftem than in others ; fuch as delirium or inflammation. 

 Hence they are liable to be abfent in company ; lit or lie long 

 in one pofture ; and in winter have the fkin of their legs burnt 

 into various colours by the fire. Hence alio they are fearful of 

 pain ; covet mufic and fleep ; and delight 111 poetry and romance. 



As the motions in confequence of fenfation are more than nat- 

 ural, it alfo happens from the greater expenditure of fenforial 

 power on them, that the voluntary motions are lefs eafily exerted.
